Skyline,

The shape of Ross' handles are very comfortable. The broad end-cap is like an anchor. They are perfect for my hands, allowing me to keep a strong yet relaxed grip on the paddle. Compared to a long list of other handles I have tested, only one other handle is close to his (BBC's pistol). 

As Ross just mentioned, the sealing reaction depends on the wood you choose (one of the advantages of handcrafted blades is that your word weights a lot). 

However, your point-question about the lacquer is a relevant one. Some people, like myself, have found sealed handles to be slippery. When I received Ross’ handle, it was still a bit slippery--he had just sealed the blade a few days before. But soon, with use, the lacquer and the slippery sensation went away. Like you, what I learned was that if I weekly sanded the handle, it would restore its beauty and will make it grippier (Ross' advice).  

If it happens that your handle comes a bit slippery like mine, as soon as the slippyness disappears because of usage, you don’t have to worry about anything. But I try to keep it as beautiful as I can. I consider this blade, not a product I would have bought at the store which I would just simply toss or use whenever I need it, but a living creation produced by an artist to which I gladly will continue to maintain.
